Why buy ambient lights, when you can have beautifully illuminated walls. Lomox has come up with stunning OLED wallpapers for your homes. When the walls are covered with OLED lightings they provide lovely low-light effects across each corner of the room. Since it requires a low operating voltage of about 3 to 5 volts and uses solar panels to juice up, it’s quite an energy efficient alternative too. I know, you must be itching to get the OLED effect on your walls, but it’s just a concept yet with no precise information on the availability.
